UniprotKB/SwissProt ID: Q8R5M8 (Q8R5M8)
Gene Name:
Cadm1
Organism: Mus musculus (Mouse)
Function: Mediates homophilic cell-cell adhesion in a Ca(2+)-independent manner (PubMed:12202822, PubMed:12799182, PubMed:12826663). Also mediates heterophilic cell-cell adhesion with CADM3 and NECTIN3 in a Ca(2+)-independent manner (PubMed:12826663). Interaction with CRTAM promotes natural killer (NK) cell cytotoxicity and interferon-gamma (IFN-gamma) secretion by CD8+ T-cells in vitro as well as NK cell-mediated rejection of tumors expressing CADM1 in vivo (PubMed:15811952). In mast cells, may mediate attachment to and promote communication with nerves (By similarity). CADM1, together with MITF, is essential for development and survival of mast cells in vivo (PubMed:15158462, PubMed:16605125). By interacting with CRTAM and thus promoting the adhesion between CD8+ T-cells and CD8+ dendritic cells, regulates the retention of activated CD8+ T-cell within the draining lymph node (PubMed:19752223). Required for the intestinal retention of intraepithelial CD4+ CD8+ T-cells and, to a lesser extent, intraepithelial and lamina propria CD8+ T-cells and CD4+ T-cells (PubMed:24687959). Interaction with CRTAM promotes the adhesion to gut-associated CD103+ dendritic cells, which may facilitate the expression of gut-homing and adhesion molecules on T-cells and the conversion of CD4+ T-cells into CD4+ CD8+ T-cells (PubMed:24687959). Acts as a synaptic cell adhesion molecule and plays a role in the formation of dendritic spines and in synapse assembly (PubMed:12202822, PubMed:23209303). May be involved in neuronal migration, axon growth, pathfinding, and fasciculation on the axons of differentiating neurons (PubMed:15707673). May play diverse roles in the spermatogenesis including in the adhesion of spermatocytes and spermatids to Sertoli cells and for their normal differentiation into mature spermatozoa (PubMed:12606335, PubMed:16612000)
